Ventilation Fans

With the correct fan, an air-handling unit can operate more
efficiently with lower noise, resulting in considerable dollar savings
over the life of the unit. Optimization of ventilation fans may
provide first-cost savings by allowing you to select a fan at a lower
price or a smaller motor and drive.

Trane Climate Changer™ air handlers offer an extensive array of fan
types and options that let you select the exact fan you need to meet
capacity. With our ventilation fans you can optimize not only to meet
the airflow and static pressure requirements, but also the acoustical,
efficiency, and discharge requirements. Variable-frequency drives for
modulation in variable-air-volume systems gives you even more precision.

Selection of ventilation fans should be based on the fan airflow
(cfm), total static pressure (TSP), efficiency (bhp), operating range,
and sound levels. Trane fan curves show fan cfm, TSP, fan rpm, and fan
wide-open cfm (WOCFM) performance relationships with the fan in the
module. The effect of the air handler casing on fan performance is
included in the fan curve. Fan curve catalogs are available from your
local Trane sales engineer.
